[Psi-devel] Patch reminder: small fixups, xep-0004/xep-0050 conformance

[Roelof Naude]

1. psi doesn't currently display xep-0004 reported items when executing
a command (xep-0050 example 8 and 9). the attached patch allows this.
i've tested against wildfire's admin commands (eg. Get list of group
members).

2. xep-0004 specifies that <instructions> may not contain '\n', instead
multiple <instructions> should be specified.

the following two patches implement that:
combine_text_of_similar_elements.patch -> added a method subTagsText
that will combine the text of similar xml elements
xdata_support_multiple_instructions.patch -> make use of subTagsText
added above.

3. here are patches to display <note> from adhoc commands:

3.1. psi.add_note_info_ahcommand.h.patch - add noteText_ & noteType_ to
ahcommand.h
3.2. psi.init_ahc_note.ahcommand.cpp.patch - initialize noteText_/Type_
from xml.
3.3. psi.display_ahc_note.patch - creates a QLabel for note display
purposes. i've concatenated the note type (info/warning/error) with the
note text. displaying an icon might be better?
